Mastering Core Care Points
Balance of Light and Temperature
As a typical positive plant, it needs to receive at least 6 hours of direct sunlight every day. It is recommended to place the potted plant on a south-facing window sill, and in winter, supplementary grow lights can be used to extend the light to 10 hours. When the temperature continues to be below 5℃, it is recommended to move it indoors for insulation.
Key Period for Water Regulation
Keep the soil slightly moist during the sprouting stage of spring and summer, and use the immersion method to water. After September, gradually reduce watering, and during the winter dormancy period, water once a month. Be especially careful to avoid waterlogging during the rainy season by tilting the pot to assist drainage.
Complete Process of Propagation and Cultivation
Division Operation Diagram
Select a 3-year-old mother plant and cut off the side buds with 3-5 leaves and roots in spring. After applying charcoal powder to the cut surface, let it dry for 24 hours, then cultivate it using a matrix of perlite:vermiculite=2:1, maintaining an environment of 18-25℃ for about 20 days to root.
Selection of Cutting Time
Softwood cutting in the plum rain season is the most effective. Select a healthy branch 8cm long, remove the base leaves, and insert it into a disinfected sand bed. Maintain a 60% shading rate and 75% air humidity, and the use of root-promoting powder can increase the survival rate by 30%.

Scales are prone to occur in poor ventilation environments and can be killed by dipping a cotton swab in 75% medical alcohol. Root rot initially manifests as shriveled leaves, promptly change the matrix to one with 30% coarse sand and treat with carbendazim solution.
Special Season Management
In the Yangtze River Valley, a rain shelter needs to be set up for outdoor cultivation, and in the northern regions, it needs to be moved indoors before November. When repotting in March every year, bone meal can be added as a base fertilizer, and dense roots can be pruned to promote new growth.
Advanced Cultivation Techniques
Controlling temperature differences can enhance the color of the leaves, maintaining a day-night temperature difference of over 10℃ in autumn. To extend the flowering period, apply potassium dihydrogen phosphate solution, spraying the leaves once every half month. For ground-planted plants, it is recommended to make a 30cm high ridge to prevent waterlogging.
